In a long action the .25-06 does everything a Roberts will do and then some. Not really. It burns around 25% more powder for a gain of a mere 7% in velocity for any given bullet as used in the .257 Roberts. Brick, what do account for the small gain in velocity with such a greater powder burn? Limited bearing surface. There's only so much additional velocity that can be had for a given bore diameter. In layman's terms, with respect to expanding gases as the powder burns, would a longer or shorter barrel affect the performance of either cartridge over the other?
"All that the South has ever desired was that the Union, as established by our forefathers, should be preserved, and that the government, as originally organized, should be administered in purity and truth." – Robert E. Lee
